my best guess is bad gas causing pinging ,that feels like a rumble/shudder. similar effect at 60mph. Watch where you buy your gas and see if the problem correlates

A dead fuel injector.
One cause would be a cold spark which means you have either a loose coil wire or a bad coil.
I encountered the same problem on my 95 Pontiac Transport 3800. An additional problem was every time it rained and the serpentine belt got wet it come off. That was caused by the combination of theTensioner being weak and the Crank Damper pulley which had moved and eating off the front row of nodules. After the local Pontiac dealers Mechanic had diagnosed the Transport, their Service Manager explained to me what the cause of my problem was. The Crank Damper Pulley moving was the primary cause of the serpentine belt moving. Replacement of the Crank Damper Pulley and the Tensioner corrected both the problems. Hope this helps you.
Connect a code scanner and see if it says anything about your Oxygen Sensor. It could also be EGR valve or PCV valve or any of a number of other potential problems.

There are a couple of things that can cause your Pontiac antilock brakes to lock up. The most common cause is a malfunctioning ABS sensor.
